EECEPTAQLE CLQSURE AND METHOD OF MAKING THE SME- applioation filled mccemher 28, 1922. Serial No. 609,367.

resident of the borough of Brooklyn, in the a county of Kings, city and State of New York, have invented certain new and useful Receptacle Qlosures and Methods of Making the Same, of which the following is a specification.

This invention relates to closures for receptacles, such as bottles or jars arranged with a thread or threads about the mouth, and in which the closure has a depending flange or skirt arranged with inwardly ex w tending projections to co-operate with the receptacle threads, the closure being adapted to he a plied to and removed from the receptacle y a'rotary movement, and it is the primary object of the invention to provide an improved closure of this character which is novel in structure, enhanced in appearance over closures of this character and ellicient in use.

In closures of this character the closure 35 flange or skirt is arranged with what is termed as a wire edge formed by rolling the edge of the skirt upon itself, and the receptacle thread engaging projections are provided. on the skirt by notching the wire an edge of the flange thereby distorting the skirt not only marring the appearance of the some, but in notching the flange large num bers of the closures are distorted to such an extent as to make themuseless as a closure, and it is a further object of the invention to provide an improved construction and arrangement of closure of this character having inwardly extending receptacle thread engaging projections in which said projections are invisible from the exterior of the closure when it is applied to a receptacle and thereby greatly enhancing the appearance and attractiveness of the closure, and in which the possibility of distorting the flange to render the same useless is reduced to a minimum.-'

It is a further object of the invention to provide an improved construction and arrangement of rolled wire edge upon the flange of a receptacle closure whereby to prevent the entrance of liquidwhich may ecome lodged on said rolled edge into the folds of the formed edge with consequent rusting and rendering the closure unsightly i d t e 555 and unsanitary an article unsalahle.

Another object of the invention relates to a method of making closures to he applied to the threaded mouths of receptacles.

@ther objects and advantages will hereinafter appear.

In the drawing accompanying and forming a part of this specification, Figure 1 is a sectional side elevation of a receptacle closure showing an embodiment of my invention.

Figure 2 is a sectional side elevation showing the method of the formation of my improved closure in one stage thereof.

Figure 3 is a side elevation, partly broken away, showing a successive stage in the method of forming the closure.

Figure 4 is a side elevation of the closure partly broken away, showing the method arranging the closure with the receptacle thread engaging means.

Figure 5 is a view looking at the bottom of Figure 1; and

Figure 6 is a sectional view of a portion of a closure and showing the manner of applying the same to a receptacle.

Similar characters of reference designate like parts throughout the different views of the drawing.

In the embodiment and method of carry ing out my invention as shown in the drawing I provide a disk and arrange the disk with a flange 7, as by drawing or otherwise, with the edge portion of the flange folded outwardly upon itself as shown at 9 in Figure 2 and a portion 10 thereof extending laterally. The laterally extending portion 10 is then rolled upon itself to arrange the-flange with a head 11, which is commonly termed as a wire edge to stiflen the flange of the disk, the folded portion 9 simultaneously with the rolling of the bead being pressed to position to lie contiguous to the flange 7 as clearly shown in Figure 3. By this arrangement of the wire edge any moisture or liquid which may become lodged thereon will not come in contact with the raw edge of the material with the consequent rusting and marring of the appearance thereof. The disk portion is also arranged with an annular depression to provide an inwardly extending bead or rib 12 for a purpose to be hereinafter described.

With the flanged disk as thus formed I arrange the same with receptacle thread onltd gaging means by notching the folded portion of the flange within the rolled edge to form inwardly extendin projections 13, said notches being circum erentially disposed around the flange at predetermined points. In the present instance there are four of these projections disposed and equidistantly spaced around the flange. These notches or projections 13 are preferably arranged at one edge of the flange and are adapted to engage below a thread or projection 14 on a receptacle 15 as shown in Figure 6. The thread engaging projections. 13 are adapted to engage a single or multiple thread upon a receptacle, preferably .a multiple thread, and the projections are so disposed around the flangeto register with the entrance portion of such thread.

To facilitate the applying of the closure to and the removal thereof from a receptacle, and to also stiffen the flange 7 corrugations 16 are circumferentially disposed around the flange to extend longitudinally thereof intermediate the folded portibn 9 and the juncture of the flange 7 with the disk portion as clearly shown in the drawing. In use a lining and sealing member, such as paratfine pa er or cork, is interposed between the e ge of the opening of the receptacle and the disk portion or top of the closure, as shown at 17 in Figure 6.

In applying the closure to a receptacle the closure is rotated and as the thread engaging projections 13 of the closure come in register with the entrance ends of the threads on a receptacle they will engage below said threads and ride along the same during the continued rotation of the closure thereby drawing the closure onto the receptacle until the top or disk portion abuts the edge to the receptacle opening and pinching the sealing material 17 firmly between the closure and receptacle. The annular rib or projection 12 is so located as to come opposite the edge of the receptacle opening, and as the disk ortion is somewhat yielding ,and the rib 12 more rigid the rib will be drawn to and accommodate itself to any irregularities or unevenness of the edge of the mouth of the receptacle opening and positively seal the same. Furthermore, the material of the flange is somewhat resilient or springy whereby the projections 13 will accommodate themselves to any irregularities in the receptacle thread, and due to such flexibility the possibility of crushing the receptacle thread or the breaking of the receptacle is reduced to a minimum as the closure is screwed home on the receptacle, while at the f same time assuring the sealing of the closure upon the receptacle.

By the construction and arrangement described it will be obvious that there is provided what in effect is a flange having a pair of concentric edges arranged substantially in the same plane with the outer edge in the form of a wire or rolled edge andthe inner edge constituting a receptacle thread engaging member. Furthermore, this arrangement of the closure not only greatly enhances the appearance thereof, since the thread engaging projections of the closure are within the wire edge of the flange and concealed thereby, but the closure may be made of relatively small d ameter and for use in connection with rece tacles having'a small neck, or mouth. 1

While I have described and illustrated in the drawing an embodiment of my invention it is obvious that variations and changes may be made in the shape, size and location of parts relative to each other, and that portions of the invention may be used without others, without departing from the scope of the invention and the meaning of the terms as expressed'in the specification and claims.

Having thus described my invention, I

. claim:

ing the lower portion of the flange out-' wardly, and upwardly forming a part of the folded portion into a bead concentric with the folded portion, and then notching the flange at the bend of the folded portion to provide the flange with inwardly extending projections interior of the bead.

3. The method of making receptacle closures, consisting in providing a disk, arrangin said disk with a depending flange and fo ding the lower portion of the flange outwardly and upwardly to lie in aplane with and contiguous to the body of the flange with a portion of said folded portion to extend laterally, then formin said laterally extending portion of the fol ed portion into a bead and corrugating the flange intermediate said bead and juncture-of the flange with the disk, and then notching the flange at the bend of the folded portion to form inwardly extehdin projections on the flange in a plane with t e bead.

4. A receptacle closure comprising a disk having a flange, said flange being partially bent outwardly and upwardly upon itself to provide a contiguous double wall flange,

and said bent flange portion being continued downwardly and then upwardly to provide a coiled head at the outer side of and concentric with the double wall of the flange with its raw edge concealed within the coil, and a plurality of notchesarranged at the edge of the flange to provide inwardly extending receptacle thread engaging projections arranged concentric with and concealed from the outer side by the bead.

5. A receptacle closure comprising a disk having a flange, said flange being folded upon itself to provide a double walled flange and the folded portion continued outward and downward to form an outer coiled bead, and said double wall of the flange arranged with a plurality of notches to pro- Vide the flange with inwardly extending projections independent of said coiled bead.

6. A receptacle closure comprising a disk having a double wall flange and the outer wall of said flange being continued down-' ward and upward to provide a coiled bead with its raw edge concealed between the outer wall of the flange and within the coil of the bead, and the edge of the double wall of the flange notched to provide the same with inwardly extending projections independent of the coiled bead.

7. A receptacle closure comprising a disk having a flange bent outwardly and upwardly from the lower edge to provide a flange with the wall of double thickness at the lower portion thereof, a bead in one piece with the folded portion of the flange formed by bending the material from the upper edge of the foldedportion of the flange outward and downward to enclose this space from above with the raw edge of the material turned inward and concealed within the bead, and circumferentially disposed portions struck inward from the edge of the material at the fold of the flange to constitute receptacle thread engaging projections arranged to be concealed by the bead when viewed from the outside with the closure applied to a receptacle.
